Longshui is the exclusive regional name of Dazu County and is also synonymous with Longshui Hardware. As early as the mid-1990s, Mou, a native of Longchang, Sichuan, discovered business opportunities while doing business in Longshui, and registered the "Longshui" trademark with the National Trademark Office. The trademark was approved in August 1998, and the approved product scope was "hoes". , harpoons, trowels, trowels, spatulas, sabers, tableware knives?, causing Longshui Hardware people to lose the "Longshui" trademark.

In recent years, a battle to revitalize and defend the millennium brand "Longshui Hardware" has been launched in an all-round way with science and technology as the guide. The trademark strategy has been included in important goals. The Party Committee and Dazu County attach great importance to it. After the county's industrial and commercial department failed to apply for administrative reconsideration to the National Trademark Office, it found that there were no hardware products with the "Long Shui" trademark on the market, but found that a trademark transfer website was selling the "Long Shui" trademark.

After learning of the situation, the county and others negotiated with the Sichuan Longchang Jupiter Food Factory run by the registered party Mou Mou for many times, ranging from asking price of 300,000 yuan to 56,000 yuan. In July this year, the county's Productivity Promotion Center formally signed a transfer contract with the registrant and bought back the registered trademark "Longshui". At present, the county is formulating management and use measures to effectively allow the "Longshui" registered trademark to play its due role. Editor in charge: Li Zhihui
